ARM Compiler

I found the reason for the crash inside SysInitFPU, it seems it uses by default the wrong FPU type. so Always -Cfvfpv2 has to be added to use the right FPU commands just to make sure I also added the -CpARMV6 to select the CPU instructions suitable for Raspberry Pi and higher. With this changes the helloworld program do not crash anymore. And also the fpc compiler works now (at least the help text).
